The SN54LVC138A 3-line to 8-line decoder/ demultiplexer is designed for 2.7-V to 3.6-V VCC operation and the SN74LVC138A 3-line to 8-line decoder/demultiplexer is designed for 1.65-V to 3.6-V VCC operation.
The 'LVC138A devices are designed for highperformance memory-decoding or data-routing applications requiring very short propagation
delay times. In high-performance memory systems, these decoders minimize the effects of system decoding. When employed with high-speed memories utilizing a fast enable circuit, the delay times of these decoders and the enable time of the memory are usually less than the typical access time of the memory. This means that the effective system delay introduced by the decoders is negligible.
The conditions at the binary-select inputs and the three enable inputs select one of eight output lines. Two active-low enable inputs and one active-high enable input reduce the need for external gates or inverters when expanding. A 24-line decoder can be implemented without external inverters and a 32-line decoder requires only one inverter. An enable input can be used as a data input for demultiplexing applications.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.
The SN54LVC138A is characterized for operation over the full military temperature range of 55°C to 125°C.
The SN74LVC138A is characterized for operation from 40°C to 85°C.
